Since the Church and Israel are made up of people, the crown is made up of people.
and a royal diadem in the hand of your God. (Isaiah 62:3) "ESV"
Keter is the crown of the tree of life. Since the tree is the axis mundi, the crown is stability and balance.
The crown is the kingdom, and the people constituting the crown are the children of the stable kingdom of God.
Let us be grateful for receiving a kingdom that cannot be shaken (Hebrews 12:28)
That cannot be shaken: stability and balance.
The kingdom of God is a network of people. Every person in the network is himself the axis mundi, because he is the temple of the living God: he is the cosmos (the orderly universe), the opposite of chaos.
The world has advanced from judgment (the tree of knowledge of good and evil) to non-judgment (the tree of life). Everyone who comes into the tree of life has entered into the eternal kingdom of God. God is not exempting anyone from his kingdom. It is a matter of free will.
I did not come to judge the world but to save the world. (John 12 47) "ESV"
This is a new beginning for all people on earth. God has wiped off the sins of the whole world and has created a new world where every human being has equal chance of entering.
“Behold, I am making all things new.” (Revelation 21:5) "ESV"
The former things are no longer important. It is no longer relevant whether a man was a Christian or a Muslim or a Jew or a Taoist or an Atheist. It is no longer relevant that a man was a murderer or a kidnapper or a rapist or a Saint. Everything done in the past belong to the past.
For the former things have passed away. (Revelation 21:4)
Everyone has an equal opportunity to change from his former self to the citizen of the kingdom of God.
The change is a transformation from the former self to the axis mundi (the Holy of Holies).
Therefore, the network of people that are the children of the kingdom is comprised of a new people whose former religious affiliations or non-religious affiliations are irrelevant. All those formerly identified as Christians, Muslims, Jews, Atheists, Hindus, Buddhists, etc., belong to the same kingdom of God.
The network is the kingdom, and the new people constituting the network are the kings and the queens in God's kingdom.
The God of heaven will set up a kingdom that shall never be destroyed, nor shall the kingdom be left to another people. (Daniel 2:44) "ESV"
Nor shall the kingdom be left to another people: the kingdom belongs to the children of Israel.
The children of Israel are those people that have repented of the divisiveness and chaos of the past and have been transformed into the reconciliation of the axis mundi.
